Distribuição e caracterização de diferentes populações de Triatoma brasiliensis Neiva, 1911 (Hemiptera, Reduviidae, Triatominae)

Ecotopes, Natural Infection and Trophic Resources of Triatoma brasiliensis (Hemiptera, Reduviidae, Triatominae)

“…From positive specimens, 15 strains were isolated, 14 of which were typed and biochemically characterized, confirming natural infection by T. cruzi (Costa et al 1996b). Regarding trophic resources, feeding eclecticism was observed for all different populations of T. brasiliensis.…”

Phylogeny of Triatoma sherlocki (Hemiptera: Reduviidae: Triatominae) Inferred from Two Mitochondrial Genes Suggests Its Location Within the Triatoma brasiliensis Complex

“…13 Triatoma brasiliensis ( Figure 1B ) was described from specimens collected in Caicó, Rio Grande do Norte state, in northeastern Brazil. 35 Lent and Wygodzinsky 15 considered T. brasiliensis melanica Neiva and Lent, 1941 and T. brasiliensis macromelasoma Galvão, 1956, as belonging to the same species as T. brasiliensis . Costa 35 reported that T. brasiliensis was in fact composed of four distinct populations: brasiliensis (Caicó, Table 2 Variable sites in 399 bp of the mitochondrial Cyt B gene for eight species of bugs …”

“…15 This characteristic led this "species" to be subjected to a multi-disciplinary study of its morphology, biology, ecology, isoenzymes, and mitochondrial DNA variation. 14,[16][17][18][19][20] It was concluded that T. brasiliensis is in fact a complex of species based on three allopatric evolutionary units: T. brasiliensis Neiva, 1911, T. brasiliensis melanica Neiva and Lent, 1941 and T. brasiliensis macromelasoma Galvão, 1956. 15 Molecular markers based on DNA have led to considerable progress in the understanding of genetic relatedness, phylogeny, and population dynamics in triatomines during the last 10 years.…”

Triatoma rubrovaria (Blanchard, 1843) (Hemiptera-Reduviidae-Triatominae) III: patterns of feeding, defecation and resistance to starvation

“…Resistance to starvation -For these studies, we essentially followed the protocol as established by Costa and Jurberg (1989), Jurberg and Costa (1989) and Costa and Marchon-Silva (1998). Thirty eggs and 30 nymphs (F1) were grouped according to their stages.…”
